Description
Technical field
The utility model patent relates to a kind of cooling apparatus of electrolyzer, particularly relates to the pressure blowing cooling apparatus that is used for aluminium cell.
Background technology
With in the process of Hall-Ai Lutefa electrolytic production of aluminum, make aluminium liquid and electrolyte melt temperature approximately be stabilized in 950 ℃ by joule effect, heat scatters and disappears away by liner and coating material layer again, and then makes whole cell body be in thermal equilibrium state.But along with the continuous increase of aluminum cell current, the heat flow rate per unit area of its cathode groove shell is also big more, and this will cause the attenuate of ledge thickness, the rising of shell temperature and the distortion of outside steel plate, thereby influences thermal equilibrium, stability and the cell life of electrolyzer.Therefore, must take effective cooling measure, improve the heat-sinking capability of pot shell.
Being intended to strengthen the method for electrolyzer sidepiece heat radiation and the patent of application has a lot, is broadly divided into three kinds of natural convection, modification groove lateral lining structure and forced convections.
First kind of natural convection cooling is by optimizing groove associated components on every side and comes regular groove air-flow on every side, and it is more smooth and easy to make it circulation, or increases area of dissipation, and then takes away more heat.The natural convection method of cooling is fairly simple, but effect is not clearly, especially under the envrionment temperature condition with higher.
Second kind of roughly thinking of revising groove lateral lining structure is embedding pipe fittings in lateral lining, by the air feed cool electrolysis cells.But this just causes inner lining structure too complicated, and exploitativeness is relatively poor.
The third is a forced draft cooling.Mainly be to lay vent-pipe, with force ventilated way cool electrolysis cells along groove.The device structure of this method is simple, and cooling performance is better.
For example the patent US 6251237B1 (corresponding to FR 2777574) by the application of Pechiney company proposes a kind of by the non-tight type refrigerating unit around pot shell air blast cool electrolysis cells.But this method is gone into potroom with a large amount of hot blows, and groove temperature is on every side risen, and has worsened the operating environment in the potroom.
Another utility model patent CN 1665963A (corresponding to US20060118410A1) of Pechiney has proposed another kind of method of cooling, be about to corresponding to the outside pot shell sealing of the electrolyzer in melt zone, and offer two inlets, a nozzle blasts air, another then is refrigerant, for example distilled water.With the refrigerant atomizing, make it to form convective heat exchange with the pot shell surface, by the heat radiation that the latent heat of vaporization is stored pot shell, by forced air flow it is taken away at last.Simultaneously, this patent has also been developed the complete circulating cooling system of a cover for this reason, with refrigerant condensation recycling.This closed system has higher cooling efficiency, but electrolyzer is too strong to the dependency of this system, just can not stop once operation; And this cooling system structure is complicated, and has additionally added equipment such as condenser, atomisation unit, has increased running cost.
Utility model patent 200620168327.0 has added the casing of a semitight on the basis of US 6251237B1, and has installed a flow deflector at box outer surface steel plate place.But this cooling system still is discharged into potroom with warm air, has worsened operating environment.
At the heat dissipation problem of aluminum cell side, all there is certain defective in above-mentioned patent, so the applicant is intended to propose a kind of simple and low-cost device and system, is used for the cooling of large-scale aluminum electrolytic cell pot shell.
